With the Nets’ last season in New Jersey officially behind them, they are finally Brooklyn-bound.

Now they just need to make sure Deron Williams is, as well.

The superstar point guard met with the media yesterday, as the Nets cleaned out their lockers following Thursday’s season-ending loss in Toronto. Though Williams made it clear he still plans on opting-out of the final year of his deal and testing free agency, that doesn’t mean he already has one foot out the door.

“I’m still looking at all of the possibilities here,” said Williams, who said he wants to have his new contract signed by the Olympics. “I went to the [Barclays Center] a couple days ago and saw how it was, and it’s going to be an exciting arena, a great place to play, and I’ve always been confident in this organization.

“Even though I was opting out, I never said I wasn’t re-signing with the Nets, and that still remains the same.”

Because of the myriad injuries the Nets dealt with this season, including Brook Lopez being limited to just five games, Williams never got a chance to see what this team was capable of. But regardless of what this group’s ceiling was, Williams knows the Nets still have work to do in order to become a championship contender.

“I think we still need some more pieces,” he said. “We would have had a playoff team. But championship, that’s another level, and I think we need some more veteran guys for that to happen.”

The Nets began a push to upgrade the roster with veteran talent during the season when they acquired Gerald Wallace from Portland. Wallace, like Williams, can opt out of his final year of his deal and become a free agent this summer. They are two of several players on the team with uncertain futures, including Jordan Farmar, who has a player option for next season, Lopez, a restricted free agent, and free agents Kris Humphries and Gerald Green.

But regardless of what happens with any of the other players on the roster this summer, the Nets’ offseason will be considered a success if Williams re-signs and a failure if he doesn’t, something Nets coach Avery Johnson readily admitted.

“Right now, especially with the season just ending, I don’t want to think about playing our first game in Brooklyn without Deron or without Gerald Green or Gerald Wallace or any of those guys,” Johnson said. “But I think what you have to do is you have to have plans and contingencies set up for most situations, and that’s part of [general manager] Billy [King’s] job and our job.”

“But right now, we’re pretty much all in on Deron, and hopefully, because we’re pretty much all in on Deron, hopefully that will pay dividends.”
